## 配置 ssh 免密登陆
- 在 cm0 上配置 ssh 可免密登陆全部服务器
```
ssh-keygen
seq -f'192.168.1.%g' 100 106 | xargs -L1 ssh-copy-id
```
- 这里的**私钥会在后面通过界面增加主机时用到**
## 关闭防火墙和 selinux
- 在全部服务器上关闭防火墙
```
systemctl stop firewalld
systemctl disable firewalld
```
- 在全部服务器上关闭 selinux
```
setenforce 0
sed -i '/^SELINUX=/cSELINUX=disabled' /etc/selinux/config
```
## 配置网络名称
- 在全部服务器上修改 /etc/hosts，增加如下解析记录
```
192.168.1.100 cm0.colben.cn cm0
192.168.1.101 gw0.colben.cn gw0
192.168.1.102 m0.colben.cn m0
192.168.1.103 m1.colben.cn m1
192.168.1.104 w0.colben.cn w0
192.168.1.105 w1.colben.cn w1
192.168.1.106 w2.colben.cn w2
```
- 在全部服务器上修改 /etc/sysconfig/network，增加各自主机名设置
```
HOSTNAME=XXXX.colben.cn
```
- 在全部服务器上设置各自主机名
```
hostnamectl set-hostname XXXX.colben.cn
```
## 配置时间同步
- 在 cm0 上配置修改 /etc/chrony.conf
```
server ntp.aliyun.com iburst
allow 192.168.1.0/24
```
- 在其他服务器上修改 /etc/chrony.conf
```
server cm0.colben.cn iburst
```
- 在全部服务器上重启 chronyd 服务
```
systemctl restart chronyd
```
## 配置 cloudera manager 内网安装源
- 在 cm0 上安装并启动 httpd 服务
```
yum install httpd
systemctl enable httpd
systemctl start httpd
```
- 在 cm0 上下载 cloudera manager yum 仓库
```
mkdir -p /var/www/html/cloudera-repos/cm6/6.3.1
wget https://archive.cloudera.com/cm6/6.3.1/repo-as-tarball/cm6.3.1-redhat7.tar.gz
tar zxf cm6.3.1-redhat7.tar.gz -C /var/www/html/cloudera-repos/cm6/6.3.1 --strip-components=1
chmod -R ugo+rX /var/www/html/cloudera-repos/cm6
```
- 在 cm0 上下载 cdh yum 仓库(**体积较小，需手动升级**)
```
mkdir -p /var/www/html/cloudera-repos
wget --recursive --no-parent --no-host-directories \
https://archive.cloudera.com/cdh6/6.3.2/redhat7/ -P /var/www/html/cloudera-repos
wget --recursive --no-parent --no-host-directories \
https://archive.cloudera.com/gplextras6/6.3.2/redhat7/ -P /var/www/html/cloudera-repos
chmod -R ugo+rX /var/www/html/cloudera-repos/cdh6
chmod -R ugo+rX /var/www/html/cloudera-repos/gplextras6
```
- 在 cm0 上下载 cdh parcel 仓库(**体积较大，可通过界面操作自动升级**)
```
mkdir -p /var/www/html/cloudera-repos
wget --recursive --no-parent --no-host-directories \
https://archive.cloudera.com/cdh6/6.3.2/parcels/ -P /var/www/html/cloudera-repos
wget --recursive --no-parent --no-host-directories \
https://archive.cloudera.com/gplextras6/6.3.2/parcels/ -P /var/www/html/cloudera-repos
chmod -R ugo+rX /var/www/html/cloudera-repos/cdh6
chmod -R ugo+rX /var/www/html/cloudera-repos/gplextras6
```
- 在 cm0 上创建 cloudera.repo，并重建 yum 缓存
```
cat > /etc/yum.repos.d/cloudera.repo <<-EOF
[cloudera-manager]
name=cloudera-manager
baseurl=http://cm0.colben.cn/cloudera-repos/cm6/
enabled=1
gpgcheck=0
EOF
yum clean all
yum makecache fast
```
- 通过界面增加其他主机时，cloudera manager 会自动部署该 repo 文件
## 安装 jdk
- 在 cm0 上安装 jdk
```
yum install oracle-j2sdk1.8
```
- 通过界面增加其他主机时，可自动安装 oracle-j2sdk1.8
## 安装 cloudera manager
- 在 cm0 上安装 cloudera-manager
```
yum install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server
```
## 配置 cloudera manager 数据库
- 在 cm0 上安装 mysql，[参考这里](/post/mysql5.7-install/)
- 官方推荐 my.cnf
```
[mysqld]
transaction-isolation = READ-COMMITTED
symbolic-links = 0
sql_mode=STRICT_ALL_TABLES
key_buffer_size = 32M
max_allowed_packet = 32M

query_cache_limit = 8M
query_cache_size = 64M
query_cache_type = 1
max_connections = 600
log_bin=/var/lib/mysql/mysql_binary_log
server_id=1
binlog_format = mixed
read_buffer_size = 2M
read_rnd_buffer_size = 16M
sort_buffer_size = 8M
join_buffer_size = 8M
innodb_file_per_table = 1
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 64M
innodb_buffer_pool_size = 4G
innodb_thread_concurrency = 8
innodb_flush_method = O_DIRECT
innodb_log_file_size = 512M
```
- 在 cm0 上启动 mysql
```
systemctl enable mysqld
